144 .IX Header "SYNOPSIS"
146 \& #include <openssl/opensslv.h>
147 \& #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
148 \& #define OPENSSL_VERSION_TEXT "OpenSSL x.y.z xx XXX xxxx"
150 \& #include <openssl/crypto.h>
152 \& unsigned long OpenSSL_version_num();
153 \& const char *OpenSSL_version(int t);
156 .IX Header "DESCRIPTION"
157 \&\s-1OPENSSL_VERSION_NUMBER\s0 is a numeric release version identifier:
160 \& MNNFFPPS: major minor fix patch status
163 The status nibble has one of the values 0 for development, 1 to e for betas
164 1 to 14, and f for release.
169 \& 0x000906000 == 0.9.6 dev
170 \& 0x000906023 == 0.9.6b beta 3
171 \& 0x00090605f == 0.9.6e release
174 Versions prior to 0.9.3 have identifiers < 0x0930.
175 Versions between 0.9.3 and 0.9.5 had a version identifier with this
179 \& MMNNFFRBB major minor fix final beta/patch
185 \& 0x000904100 == 0.9.4 release
186 \& 0x000905000 == 0.9.5 dev
189 Version 0.9.5a had an interim interpretation that is like the current one,
190 except the patch level got the highest bit set, to keep continuity. The
191 number was therefore 0x0090581f.
193 \&\s-1OPENSSL_VERSION_TEXT\s0 is the text variant of the version number and the
194 release date. For example,
195 \&\*(L"OpenSSL 1.0.1a 15 Oct 2015\*(R".
197 \&\fBOpenSSL_version_num()\fR returns the version number.
199 \&\fBOpenSSL_version()\fR returns different strings depending on \fBt\fR:
200 .IP "\s-1OPENSSL_VERSION\s0" 4
201 .IX Item "OPENSSL_VERSION"
202 The text variant of the version number and the release date. For example,
203 \&\*(L"OpenSSL 1.0.1a 15 Oct 2015\*(R".
204 .IP "\s-1OPENSSL_CFLAGS\s0" 4
205 .IX Item "OPENSSL_CFLAGS"
206 The compiler flags set for the compilation process in the form
207 \&\*(L"compiler: ...\*(R" if available or \*(L"compiler: information not available\*(R"
209 .IP "\s-1OPENSSL_BUILT_ON\s0" 4
210 .IX Item "OPENSSL_BUILT_ON"
211 The date of the build process in the form \*(L"built on: ...\*(R" if available
212 or \*(L"built on: date not available\*(R" otherwise.
213 .IP "\s-1OPENSSL_PLATFORM\s0" 4
214 .IX Item "OPENSSL_PLATFORM"
215 The \*(L"Configure\*(R" target of the library build in the form \*(L"platform: ...\*(R"
216 if available or \*(L"platform: information not available\*(R" otherwise.
217 .IP "\s-1OPENSSL_DIR\s0" 4
218 .IX Item "OPENSSL_DIR"
219 The \*(L"\s-1OPENSSLDIR\*(R"\s0 setting of the library build in the form \*(L"\s-1OPENSSLDIR: \*(R"..."\*(L"\s0
220 if available or \*(R"\s-1OPENSSLDIR: N/A"\s0 otherwise.
221 .IP "\s-1OPENSSL_ENGINES_DIR\s0" 4
222 .IX Item "OPENSSL_ENGINES_DIR"
223 The \*(L"\s-1ENGINESDIR\*(R"\s0 setting of the library build in the form \*(L"\s-1ENGINESDIR: \*(R"..."\*(L"\s0
224 if available or \*(R"\s-1ENGINESDIR: N/A"\s0 otherwise.
226 For an unknown \fBt\fR, the text \*(L"not available\*(R" is returned.
228 .IX Header "RETURN VALUES"
229 \&\fBOpenSSL_version_num()\fR returns the version number.
231 \&\fBOpenSSL_version()\fR returns requested version strings.
